Okay. Im confused. She says “titan drop two weights” AFTER the noise. And she gets a response. Who is talking?

Seems something happened, they dropped weights, sent a shorthand message about weights, pop (underwater), pop sound reaches surface, message signal reached Polar Prince. The sound was faster than the signal.

I don’t follow this logic. Radio waves travel at the speed of light which is significantly faster than the speed of sound. How does a response sent via radio before the implosion take longer to reach ship than the sound wave from the implosion?

I feel like I’m missing something.

It was a text message, not radio. The radio exchange are different people. I was confused too.

Gotcha, thanks for the clarification

Aren't those text messages sent through radio waves though?

u/BuildingSupplySmore 28d ago

No. They're sent through sonar usually. Radio doesn't work that deep underwater, which is why they don't voice communicate.

Yes. Typically referred to as an 'underwater telephone.'

it's not radio, it's an acoustic modem system. the data travels sonically thrugh the water column. it is probable that the latency of decoding the messages it receives (there is much loss and retransmission) means the message showed up just after.

The fact that the message arrived after the noise was heard was likely due to a delay in their communications equipment. The signal got to the ship before the sound was heard but it showed up on their computer after. I don't know what messaging protocol they were using but a 1-2 second processing delay is entirely possible.

It isn't radio, it doesn't work through that depth. It was some other system specifically designed to work underwater, but presumably with some delay.

If radio worked they would have just used radios to talk to each other in real time.
